What is the recommended following distance in a non-emergency situation?

• A. 2 seconds behind the vehicle in front of you
• B. 3 seconds behind the vehicle in front of you
• C. 4 seconds behind the vehicle in front of you
• D. 1 second behind the vehicle in front of you

Answer: (B)

Maintaining a safe following distance gives you time to notice a hazard, react, and stop without a crash. In normal, non-emergency driving, the standard guideline is to keep about a three-second gap behind the vehicle ahead. This amount of space provides a reliable buffer to brake smoothly if the lead vehicle brakes suddenly and helps accommodate slight delays in perception and reaction.

Two seconds is thinner than ideal for many speeds and conditions, and four seconds is more conservative—useful in wet, snowy, or foggy weather, or when following a large/heavy vehicle. One second is clearly unsafe, offering almost no time to react.

To check your distance, pick a fixed object on the roadway. As the lead vehicle passes it, start counting seconds. If you reach three seconds before your vehicle reaches that same object, you’re at a safe following distance. If you don’t, increase the gap accordingly.
